For those of you who dislike anything too cutesy, consider using grown-up furnishings in the nursery.
With the exception of this great aqua crib, nothing in the room screams baby. The pale grey painted walls, hot pink patterned wallpaper, crystal chandelier and dark wood dresser are all "grown-up" items. You can get an interesting and sophisticated looking nursery by shopping in your favorite home furnishing stores or repurposing items you already own.
